Default 1.6 puking oil out dipstick

The title says it all. My 1.6 NA is puking oil out the dipstick. 210K miles. The gauge reads about 15-20 psi at road speed. I had all the seals replaced in January and have recently replaced the PCV valve (which changed nothing).

Any suggestions???

Breather hose clogged? Pull them both off (PCV and breather hose) and make sure air goes through each of them.

Also, do a compression check to check for a broken piston ring.

I'll give the breather hose a shot. The compression was good on all four before I did the seals. But that was then...... Maybe I will start looking for another 1.6 engine.

Thanks for the advice.
